Comments: The PN reconstruction presents some difficulties. Chech. points to *-u- in the 2d syllable (doʕaχ < *daHuχ), Ing. - to *-i- (dīχk < *daHiχ-iḳ with a diminutive suffix) and Bacb. - to *-e-. Final -ʔ in Bacb. is probably a re- sult of assimilation (spirant -χ > laryngeal); anyway, it is impossible to separate the Bacb. form from Chech. and Ing. The word belongs to the 3d class in all languages.
